Potassium oxide (K 2 O) is an ionic compound of potassium and oxygen. ... The chemical formula K 2 O (or simply 'K') is used in several industrial contexts: ...
Potassium superoxide is an inorganic compound with the formula K O 2. [6] It is a yellow paramagnetic solid that decomposes in moist air. It is a rare example of a stable salt of the superoxide anion. It is used as a CO 2 scrubber, H 2 O dehumidifier, and O 2 generator in rebreathers, spacecraft, submarines, and spacesuits.
Potassium is a chemical element; it has symbol K (from Neo-Latin kalium) and atomic number 19. It is a silvery white metal that is soft enough to easily cut with a knife. [9] Potassium metal reacts rapidly with atmospheric oxygen to form flaky white potassium peroxide in only seconds of exposure.
[13] [14] Does not contain potassium oxide (K 2 O), which plants do not take up; [15] the amount of potassium is often reported as K 2 O equivalent (that is, how much it would be if in K 2 O form), however, to allow apples-to-apples comparison between different fertilizers using different types of potash. Caustic potash or potash lye: potassium ...

Example: sodium chloride, potassium oxide, or calcium carbonate. When the metal has more than one possible ionic charge or oxidation number the name becomes ambiguous. In these cases the oxidation number (the same as the charge) of the metal ion is represented by a Roman numeral in parentheses immediately following the metal ion name.
An oxide (/ ˈ ɒ k s aɪ d /) is a chemical compound containing at least one oxygen atom and one other element [1] in its chemical formula. "Oxide" itself is the dianion (anion bearing a net charge of –2) of oxygen, an O 2– ion with oxygen in the oxidation state of −2. Most of the Earth's crust consists of oxides. Even materials ...
For instance, in the compound K 2 O, potassium (K) is a metal and therefore its proper name is potassium oxide, rather than potassium monoxide. Among monoxides, carbon monoxide and dihydrogen monoxide are both neutral, germanium(II) oxide is distinctly acidic, and both tin(II) oxide and lead(II) oxide are amphoteric.
